The map is the work of Slate's Eric Holthaus and Chris Kirk, who used the recent update to the World Resources Institute's data on carbon emissions to put it together. You can see the full map over at Slate, where Holthaus and Kirk have also compiled a look at some of most game-changing times and places in the history of carbon emissions.
